GENERAL DESCRIPTION

The TOA SF-30 is a 3-way loudspeaker system capable of
being suspended from the ceiling. The system consists of
bass-reflex enclosure housing a hevy-duty 12-inch woofer,
a constant directivity horn coupled with high-efficiency
compression driver, and an exponential horn tweeter. The
constant directivity horn ensures a uniform dispersion pat-
tern of 90 degrees horizontal and 40 degress vertical.
A high-tech crossover network of –18dB/octave slope is
used for crossover between the woofer and the driver.
This combination results in an extended smooth frequency
response and wide coverage area. The system will handle
120 watts RMS of continuous pink noise and 360 watts of
continuous program material.
The rear panel provides ¼" phone jacks and screw-type
terminals for full-range operation. The phone jacks can be
converted into XLR connectors by removing mounting
panel and installing XLR connector. The mid and high fre-
quency level controls are provided on the side of the en-
closure.
T-nuts for mounting brackets for ceiling suspension are
provided on the rear slant and on both sides of the enclo-
sure.
Enclosure is finished in grey polyester. The black punched
metal front grill is removable.
FEATURES
1. Three-way vented system.
2. Extended smooth frequency response.
